STEAM-ENGINE LU BRICATOR.

SPECIFICATION forming part of Letters Patent No. 441,093, dated November 18, 1890. Original application filed October 30, 1889, Serial No. 328,625. Divided and this application filed A gust 4, 1890. Serial No.

In the accompanying drawings, Figure 1 is a vertical section of my engine on a plane parallel to and through the axis, the central parts being shown in elevation; and Fig. 2 is a like View of the same 011 the linexxof Fig. 1.

The subject-matter herein shown and described was first shown and claimed in my application, Serial No. 328,625, filed October 30, 1889, and this case is the result of a division thereof.

A designates the frame or case, on which is mounted the crank-shaft B in any suitable bearings, said shaft carrying the crank 16, connected by any suitable connection to the piston-rod 17.

At the lower end of the frame or case is the lubricating-chamber O, the bottom of which is formed by the diaphragm 19, and below which is the settling-chamber D. The diaphragm or division 19 is provided with one or more perforations 20 leading to the settling-chamber, which perforations are covered by curved plates 21 fastened to the diaphragm at one side, so as to form an indirect passage-way from the lubricating to the settling-chamber.

Leading from the lower part of the settlingchamber there is a pipe 22, that extends up- (No model.)

ward to the height desired to be maintained for the. water and oil in the lubricating-chamber. The crank-shaft so agitates the combined oil and water as to somewhat mix them, although the oil has a tendency to rise to the top. By means of the division or diaphragm having only indirect passages leading from the lubricating-chamber to the settling-chamher the motion of the crank-shaft is not imparted to said settling-chamber and the oil may riseto the top. In case condensed steam falls down into the lubricating-chamber the surplus water Will escape through the pipe 22, leaving the oil on the top of the water within the settling and lubricating chambers, and thereby prevent the waste of oil that would occur in this engine Without the diaphragm 19. Y

I claim as my invention 1. The case or frame having a lubricatingchamber and settling-chamber, with the diaphragm or division 19 between them, said diaphragm having the openings 20 and curved plates 21 for making an indirect passage through said diaphragm, and said settlingchamber being provided with the escape-pipe 22, substantially as described, and for the purpose specified.

2. In an engine-case, the combination of a lubricating-chamber, a settling-chamber below the saine,adivision between the two having indirect passages from one chamber to the other, and an escape-pipe leading from the settling-chamber, substantially as de scribed, and for the purpose specified.
